- Proper Disposal: Dispose of used blades safely according to local regulations.
- Intended Use: Use this tool only for its intended purpose of cutting circles in appropriate materials.
Setup
- Unpack Components: Carefully remove all items from the packaging.
- Prepare Work Surface: Place the non-slip mat on a clean, flat, and stable work surface. This will help prevent the material from shifting during cutting.
- Install Blade:
- Locate the blade holder on the circular cutter.

Operating Instructions
Follow these steps to cut circles with your DSPIAE MT-EC Circular Cutter:
- Place Material: Position the material you wish to cut on the non-slip mat. Ensure it is flat and secure.
- Set Cutting Diameter:
- The cutter allows for stepless adjustment of the cutting diameter.
- Loosen the adjustment screw on the cutter's arm.
- Slide the blade holder along the arm to achieve the desired radius. The cutter supports a minimum cutting diameter of 1mm and a maximum of 50mm.
- Once the desired radius is set, tighten the adjustment screw to lock the blade holder in place.
- Position Cutter: Place the central pivot pin of the circular cutter at the exact center of where you want your circle to be cut.
- Begin Cutting:
- Apply gentle, even downward pressure on the cutter.
- Rotate the cutter smoothly around the central pivot pin.
- For thicker materials, multiple light passes may be more effective than a single deep cut.
- Ensure the blade cuts through the entire thickness of the material before removing the cutter.
- Remove Cut Circle: Carefully remove the cut circle and any excess material.
Tip: Practice on scrap material first to get a feel for the cutter and to determine the optimal pressure and number of passes for your specific material.
Maintenance
- Cleaning: After each use, gently wipe the cutter with a dry, soft cloth to remove any dust or material residue. Do not use harsh chemicals or abrasive cleaners.
- Blade Replacement: Replace the tungsten steel blade when it becomes dull to ensure clean and precise cuts. Refer to the "Setup" section for blade installation instructions.
- Storage: Store the circular cutter in a dry, safe place, away from moisture and direct sunlight. Keep it in its original packaging or a protective case to prevent damage and accidental contact with the blade.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Uneven or rough cuts | Dull blade, insufficient pressure, unstable material, incorrect blade depth. | Replace blade, apply more consistent pressure, ensure material is secure on non-slip mat, adjust blade depth if possible. |
| Cutter slips during operation | Material not secured, non-slip mat not used, insufficient downward pressure on pivot. | Ensure material is firmly placed on the non-slip mat, apply steady downward pressure on the central pivot. |
| Difficulty rotating cutter | Blade holder screw overtightened, debris in mechanism. | Loosen blade holder screw slightly, clean any debris from the cutter's moving parts. |
